The 104 Field Battery, Royal Australian Artillery was formed in the town of Moascar in Egypt during March 1916 during the First World War, as the 104th Field Artillery (Howitzer) Battery, part of 4th Field Artillery Brigade. The battery was disbanded in 1919, but the name was used for a new battery raised in 1965, which later formed part of the Auustralian military involvement in the Vietnam War. It is now one of three gun batteries in 1 Regt RAA. History World War I The 104th Field Battery, Royal Regiment of Australian Artillery, had its beginnings in Egypt, in March 1916. At this time the Battery was raised as a part of the general expansion of divisional artillery prior to the AIF being dispatched to France. In mid-March 1916 the battery sailed for France, and upon their arrival were issued with new 4.5 inch howitzers, reunited with their horses and commenced training. On 21 April 1916, 104th Howitzer Battery relieved C Battery of 176 Brigade Royal Field Artillery (RFA) on the line south east of Armentières, exchanging guns in the process. Shortly after this, they were deployed to the Somme and saw their first real action on the Western front. After the Third Battle of Ypres, the battery fired in support of the British 30th Division and the British 7th Brigade in the Battle of the Hindenburg Line. Over the next two years, the 104th Field Battery, as part of the 2nd Division Artillery, saw intense and unrelenting action on the Western Front, with almost 58% of the total gunners deployed from Australia being killed. After victory was declared the battery returned to Australia and was disbanded. In the Second World War, the previous practice of having independent artillery batteries was abandoned in favour of allocating batteries to artillery regiments, and so the 104th title was not used in that conflict. Vietnam War The 104 Battery name was revived in September 1965 as a medium battery equipped with BL 5.5-inch medium guns, but in 1967, these were replaced by M2A2 howitzers, changing its designation to a field battery. The unit served two tours of South Vietnam; the first was from May 1968 to May 1969 as part of 12 Field Regiment, supporting 4 RAR. On returning to Australia, the battery regrouped in Holsworthy, and moved up to Townsville in preparation for its second tour of Vietnam. The battery's second tour
